The rocket thrust-chamber's supersonic exhaust jet makes a deafeningly loud ( 130 decibels ), shrill screeching sound, very different from the roar of an airplane's jet engine.

The last rocket thrust, along with Eros'minuscule gravity, allowed NEAR to bounce, perhaps as high as 100 meters, said some engineers, and then to settle on the surface.
13.
Rotating the ring in this manner would require the ring stations to use powerful rocket thrust, requiring both large rocket systems and a large amount of reaction mass.
14.
The ground testing of the Nuclear thermal rocket engines intended for the Saturn C-5N's, in-space 3rd stage, still hold a number of combined rocket thrust and specific impulse records.
15.
The missiles are the third generation of the 30-year-old Hawk system, and shorten reaction time by tripling their rocket thrust and permitting multiple targeting, the military spokesman's office said.
16.
The Space Shuttle, while far faster than the X-43 or X-15, was not regarded as an aircraft during ascent as it was carried ballistically by rocket thrust, rather than the air.
17.
For instance, the Rocket-based combined cycle ( RBCC ) engine uses a rocket engine inside a ramscoop so that at low speed, the rockets thrust is boosted by ejector augmented thrust.
18.
Liquid rocket fuel is better in use because the rocket thrust can be adjusted mid-flight unlike solid rocket fuel that burns at a fixed rate without any mechanism to alter it.
19.
The Lunar Rover allowed the astronauts to travel fairly quickly over a few miles, but an improved version of the LESS could allow rapid travel over much longer distances on rocket thrust.
20.
A series of rocket firings starting in May will lower the orbit of the Compton Gamma-Ray Observatory, and a final rocket thrust will send the craft into its fiery plunge on June 3.
